PURPOSE:To recognize the approximate position of an assigned area by simultaneously storing the country corresponding to the assigned area and displaying the time difference of the two different areas by display of the country simultaneously with the display of the area or(and) by the time difference of the above- mentioned reference area. CONSTITUTION:The world timepiece not only displays the areas but simultaneously displays the country name of said area. This display is attained as the areas and the country names thereof are stored in a corresponding relation in the memory region 30C of a calendar memory part 30 and the country name is displayed together with the area by reading out the stored areas and the country names. The difference in the time is, therefore, recognized within the circumference and the easy knowing of the time in the desired area is enabled. In addition, the country of the searched area is possible and the approximate judgment of in which place such area exists is enabled as well.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electronic clock, and particularly to a world clock that can output and display the time of each region of the world.

<Prior Art> There are electronic clocks that can not only display the time in the country where the user lives, but can also display the time in various parts of the world.

This is done by taking one region as Hanfu and finding the time difference for each region with that region, and by calculating the time difference and clock time, it is possible to know the time in each region. can. Although this can be calculated by the user himself, there are electronic world clocks that memorize each region and time difference, read this out as necessary, and calculate it electronically.

<Problems to be solved by the invention> According to the electronic world clock as described above, for example, the seventh
As shown in Figure (a), only the area name (display part i) and time were displayed. Therefore, it is often difficult to know which country the region is from.

In Japan, there is only one standard time regardless of region, so there is no chance of getting the time wrong. However, in the United States, standard time differs for each region. Therefore, if only the region and time are displayed, the user may mistakenly believe that only one standard time exists in that country.

Therefore, even if users can understand the country in the displayed region, they often misunderstand that there is only one standard time in that country, and confuse the times in each region within the same country.

Furthermore, in order to know the time between two regions, it is necessary to search for two different regions to find out the time, which is a very troublesome operation.

In view of the above points, the present invention has been developed not only in each region of the world, but also in
By displaying the country names of the regions at the same time, the above-mentioned mistakes can be prevented, and a world clock can be provided that can easily tell the time between different regions.

Means for Solving Problems〉 The world clock of the present invention, when displaying the time of each calculation place,
It is characterized by simultaneously displaying the region and country name at that time, or the time difference between a specific region and a specified region.

Effect> According to the world clock of the present invention, a designated region and the country of that region can be displayed simultaneously. Therefore, for example, because the time in various parts of the United States is different, it can be seen that the standard time is different in each place. Therefore, you can search for the area you need and know the exact time.

Additionally, since the time difference between a specific region and the designated region is displayed, it is easy to recognize the current state of the specified region by looking at the time difference between the currently displayed designated region.

<Example> FIGS. 1(a) and 1(b) show external appearances of an electronic device according to the present invention that also has many other functions including a calendar function, such as an electronic notebook that can also be used as an electronic desktop calculator. FIG. 2 is a perspective view and a plan view of FIG.

The electronic notebook according to the present invention has a calendar display function, a schedule function (a function including input/output), a world clock, and a calculation function capable of performing at least four arithmetic operations.

As shown in the figure, the electronic notebook includes an operation section I and a display device 2. The operation unit 1 includes human keys 11 for calculations, etc., consisting of a value number key for performing calculations and an operation instruction key. Character input key I2, cursor movement key 13 for specifying the position of character input, date of calendar, etc., edit key 14 for character control such as inserting and deleting characters, and for turning on or off the power of the electronic notebook main body. power key I5
It also has a mode (function) selection key 16 for setting each mode such as a calendar function, a schedule function, a world clock function, a clock display function, and a calculation function.

In addition, the display unit 2 has an L
This is a display device consisting of a CD or the like. This display device 3 can display a large number of lines, and is designed so that characters can be displayed in a dot matrix of, for example, 5×7.

The electronic notebook is set to that mode by operating one of the mode selection keys I6. For example, as shown in FIG. 2, when the power is turned on using the power key 15, a state is set in which various modes can be selected. Here, by turning on the power key 15, the computer mode may be set preferentially.

Calculation key 16! By operating , calculation mode is set. Calculation results, formulas, etc. are displayed in a format as shown in FIG. 3(a) or (b).

When the clock key 162 is operated, the time counted by the clock circuit is displayed, for example, as shown in FIG. 7(a). When the clock key 162 is operated at the same time as or after the 5HIFT key 111 is operated, a mode is set in which the area being counted by the clock circuit is changed.

By operating the world clock key 163, the time in various parts of the world can be displayed. An example of the display is shown in FIG. 7(b). Here, when adjusting the time, if the world clock key 163 is operated at the same time as or after the operation of the 5HIFT key 111, the time adjustment mode is set.

By operating the schedule key 164, it can be used as a schedule management device that can input and output a schedule. Examples of the display are shown in FIGS. 4 and 5. In addition, by operating the schedule 164 at the same time as or after operating the 5IIIFT key 111, a second
Enabling scheduled manpower.

By operating the calendar key 165, a calendar for 1t months is displayed, for example, as shown in FIG. 6(a). This display is a common one that indicates Sunday as the first day of the week. On the other hand, when displaying Monday as the first day of the week, for example, by operating the calendar key 165 at the same time or after operating the 5t (IFT key Ill), a calendar display as shown in FIG. 6(b,) can be displayed. enable.

The above is an outline of the various functions provided in the electronic notebook. Next, each function will be explained.

Calculator Mode As described above, when the calculation key 161 of the mode selection key I6 is operated, the calculation mode is set.

In this calculation mode, the value number key and operator key -1
By operating the various keys 1, input numerical values are displayed in order, and the calculation results are displayed as shown in FIG. 3(a). This is similar to the conventional one-level display.

Also, by continuously operating the calculation key tet,
For example, in a calculation process by hand, numerical values and operation symbols are displayed at the same time. An example of the display state is shown in Figure 3 (,).
Shown below.

As described above, in the computer mode, the calculation key 161
Depending on whether the calculation process is operated continuously or once, it is selected whether the calculation process is displayed in one stage or in multiple stages. In this way, you don't have to select the display state by operating the calculation key, but by operating other keys in the calculator mode! It may be possible to select whether to use membrane display or multi-stage display.

Calendar Function Next, the calendar function will be explained. As for the calendar function, when the calendar key 165 of the mode selection key 16 is operated, a calendar for January 1988 is displayed on the display device 2, for example, as shown in FIG. 6(a). In this display, Sunday is displayed as the start of the week, but
Monday can also be displayed as the start of the week, depending on the country. This will be explained in detail later. Also, the 6th
In the calendar display in Figure (a), the cursor position is indicated on the 11th to make that day more prominent than other days. The position of this cursor can be freely moved vertically and horizontally using the cursor movement key 13.

Further, the display portion indicated by the symbol a displays the number of days from January 1st of the year to the date indicated by the cursor. The display section also shows the number of days remaining from the date indicated by the cursor to the last day of the year (December 31st). The display gI5c indicates what week of the current year the day indicated by the cursor falls on. That is, each of the above-mentioned display sections a, b, and C indicates that January 11th is the 11th day 1 from the first day of the year, 355 days remaining, and the second weekday. The display section C is displayed in reverse.

When displayed in this way, it is possible to recognize at a glance the number of days remaining from today's date and the number of days since January 1st. Therefore, the number of days from a certain date to a specific date can be easily calculated from the number of days displayed on the display section a. That is, if the number of days displayed on display section a on a certain day is A, and the number of days displayed on display section a on a specific day is B, it can be easily calculated by B-A (where A<B). This means that when the year changes, if you add the number of days in display part A from the first day of that year to the number of days in display part A of the previous year, you can easily change the number of days from a certain date even if the year spans. You can determine the number of days until the date. Note that the inverted display on the display section d indicates the day when the second schedule 1 is required.

Schedule function When the schedule key 164 is operated, the schedule mode is set. Therefore, if a schedule has been input, the stored schedule contents are displayed together with the time, as shown in FIG. 4(a), for example. if,
If no schedule input has been made, the time and schedule details will be displayed without being displayed. When manually creating a schedule on a display screen like this,
By inputting the date, time, schedule details, etc., the information is stored in the storage section. Further, FIG. 4(b) shows a schedule display in a state where no time input is performed. Here, the display part e shows the date, the display part f shows the start time and the end time, and the display part g shows the presence or absence of an alarm.
If an alarm is required, a bell mark will be displayed. The display section also displays the contents of the schedule.

Unlike the schedule mode described above, from the calendar display state, by operating the calendar key 165, a schedule display as shown in FIG. 5, for example, is performed.

For example, in the display state of FIG. 6(a), when the calendar key 165 is operated, the schedule contents for one week from the 11th indicated by the cursor are displayed as shown in FIG. 5(a). As shown in the figure, the date, day of the week (initial letters), and schedule contents for that day are displayed using a predetermined number of characters from the beginning.

In addition, in the schedule display state of FIG. 5(a),
When the calendar key 165 is operated, the schedule for that day, indicated by the cursor, is displayed as a time graph as shown in FIG. 5(b). In other words, the start and end times of the schedule are displayed in a graph.

This time display part is shown in, for example, 1 hour type,
By displaying a graph according to the time unit, the start time and end time of the schedule can be recognized.

Here, "H" or "do" or "-0" is displayed at the top or bottom of the graph. For example, if you explain this in terms of the cursor display position, this means that from after 9 o'clock, 1
It shows the scheduled time until 1 o'clock. That is, if the time is up to 11 o'clock, "I" is displayed, and if it is past 111 o'clock, "-" is displayed. Also, if the start time is 11:00, change "G" to 11:00.
If the start time is past the time, it will be displayed in the form of a symbol such as "-". This is often done manually by setting the start time on the hour or in 30-minute increments when inputting the time of the schedule. Therefore, if the hour is input, a display indicating the break is made as the start or end of the hour, and if the hour starts or ends, the above display is made.

Therefore, if the input is made in 30-minute units, it can be easily determined from the graph display whether it is the start or end of the hour or the start or end of the 30-minute period. However, the display shown in Figure 5(b) is just an example, and if the display is to be displayed in a format that distinguishes whether it is on the hour or beyond, it would be helpful to indicate the start or end of the schedule. You can easily determine the time.

In addition, although the above explanation has been made in units of 30 minutes, the above-mentioned division display may be performed, for example, in order to determine whether the start time is 0 to 29 minutes or 30 to 59 minutes.

Here, when inputting a schedule, it is necessary to input the year, month, day, day of the week, etc. However, there is a schedule that has a fixed month and day every year.

For example, each holiday, the birthday of a family member, acquaintance, friend, etc.
There are wedding anniversaries, etc.

It used to be necessary to input the date and time manually every year, but by simply inputting the month, day, etc., it is now possible to display the schedule for the days established each year.

In other words, it is possible to input a second schedule that does not limit the year.

Regarding the above input, 5) operation of the IIFT+schedule key 164 sets the schedule input state. With this setting, you do not need to enter the year, you can enter the month and day of the week, or the month and the day of the week, and enter schedule details such as holidays, birthdays or wedding anniversaries, Mother's Day and Father's Day, etc. By doing so, the schedule is stored in the determined storage unit. This schedule content can be displayed by changing the date in the calendar display as shown in Figure 6 (a).
On the display screen, as shown in the display section d, it is distinguished by an inverted display. To find out what this date and time means, move the cursor to that day and operate the schedule key to display the contents of the schedule for that day, as shown in FIG. 4(b). In this case, as a matter of course, the time is not displayed.

Clock function The clock or world clock mode is set by operating the clock key 162 or the world clock key 163. For example, a clock has a function of displaying the country where the user who owns the electronic notebook is located as a home region (specified region), and a function of a world clock that displays the world time.

When displaying a clock, by operating the clock key 162, the current time that the clock circuit is currently measuring is displayed as shown in FIG. 7(a). Here, the display part i shows the area where the clock is displayed, the display part j shows the country name of the area, the display part shows the year, month, and day, and the display part 1 shows the time.

In addition, to select the world clock mode, use the world clock key 16.
3, a screen as shown in FIG. 7(b) will be displayed. Here, the major difference from the clock display is that
The time difference is displayed on the display section m. This indicates the time difference between the time in the home area (specified area) where the clock circuit is counting time and the time in the area displayed in FIG. 7(b). If your home is 'NEW YORK' in the US, it is 'LON' in the UK.
It can be recognized that the time difference with "DON" is 5 hours. Also, + indicates that the time is ahead of the home.

The electronic notebook having each of the functions described above is realized by the circuit configuration shown in FIG. In the block circuit, 3
4 is a program I'IOM which stores a program for operating the electronic notebook of the present invention, and 4 is a central processing unit (CPU) 5 which transmits key human power signals operated by the key human power device 1.
It is an input/output device (Ilo,) for manual input to the computer.

Further, the dot matrix display device 2 has a drive circuit lO
Necessary information is displayed according to the CPU 5 via.

Further, 30 is a calendar storage ROM that stores each year's calendar, and 6 is a clock circuit that counts the current time of the home area. Further, numeral 7 is a register that temporarily stores necessary information when necessary, 8 is a schedule storage unit that stores and can read input schedules, and 9 is a register that stores and reads out the date and time of the schedule enacted every year. possible second
This is a schedule storage section. The storage units 8 and 9 may use part of the RAM, which is a temporary storage register provided in the electronic notebook, but may be stored in the rlAM of an IC card that is removably provided in the electronic notebook. More. In other words, by replacing the IC card, it is possible to add functions and store necessary data such as storing phone numbers and train times instead of storing schedules.

Next, the contents of each storage section will be explained in detail.

Calendar storage ROM 30 The calendar storage ROM 30 stores, for example, the year in the Western calendar and the month of January corresponding to that year in the storage area 30A! I remember the day of the week. This day of the week is converted into a number and stored. According to the present invention, Sunday is set to "0" and Saturday is set to "6".

Therefore, since January 1st of 1988 is stored as "5", the CPU knows that January 1st is a Friday.
5 and is processed, and a one-month calendar as shown in FIG. 6(a) is displayed on the display device 2.

In addition, the storage area 30B of the calendar memory R, OM 30 stores the number of days in each month in normal years, the number of days in each month in leap years, and the number of days from January 1st to that month, differentiated into normal years and leap years. are doing. In other words, the number of days until February 1st is the same in normal years and leap years, but the number of days until March 1st is different between normal years and leap years.

Therefore, normal years and leap years are remembered separately.

Furthermore, the storage area 30C is not related to storing the calendar, but stores information such as regions and time differences according to the world clock, as shown in FIG. To explain in detail with reference to FIG. 9, there are a storage section (30C-2) for the region corresponding to each address (30C-1), a storage section (30C-2) for the country name of the region.
3), and a storage unit for the time difference from the reference area (30C-4
). Therefore, by specifying an address, the region, country name, time difference, etc. of each storage unit corresponding to that address will be read out at the same time.

The schedule storage unit 8 stores each piece of information on a manually-generated schedule. The schedule storage unit 8 is
Storage area 8A stores the year, month and date, 8B stores information indicating whether or not to output an alarm, 8C stores the alarm time, 8D stores the schedule start time, 8E stores the schedule end time, and 8F stores the contents of the schedule.

For example, the schedule in the area in which the year, month, and day measured by the clock circuit 6 matches the storage part 8A of the schedule storage part 8 is read out.

Second Schedule Storage Unit 9 The second schedule storage unit 9 is distinct from the schedule storage unit 8 and stores information on a second schedule.

In other words, it memorizes five reports (month and day of holidays, wedding anniversaries, birthdays, etc.). The second schedule storage unit 9 has a storage area 9A.
, 9B, 9C, and 9D store the first day of the month, the day of the week, and the week of the month, and 9E stores the contents of the schedule. For example, if a schedule related to the month is stored in the calendar display, the second schedule storage section 9 is used to search for the schedule and display the related day in reverse video.

Second Slow Register 7 The temporary storage register 7 is used to store necessary information (for example, flags, etc.) and the following information under the control of the CPU 5. In other words, the area 7A of the -time storage register is used to store the time measured by the clock circuit 6 each time. In this area 7A, the year, month, and day are stored. In addition, the area 7B corresponds to (a' in FIG. 6) in the calendar display.
or (b) is used as a flag for selecting whether to display. The area 7C is used as a second schedule input as a mode setting flag for selecting the month, the day of the week, and the day of the week for manually inputting the month and day. Furthermore, area 7
D is used to store the address of one of the world regions in watch mode.

In other words, the address stored in 7D determines the clock display for the first region in world clock mode.

Further, the - hour storage register 8 includes storage sections XI to X5 for executing each calculation in the calendar display.

The control operation of the block circuit shown in FIG. 8 will be described below in detail for each function with reference to flowcharts and display states for each function.

Control operation in computer mode.

In computer mode, if you press calculation key +61, the CPU
5 is set so that it can perform calculations in response to the key operation. That is, in the flowchart of FIG. 2, when the computer mode is set, the CPU 5 performs control according to the flowchart shown in FIG.

After determining the operation of the calculation key 161 (step Of), the input state of the calculation key 161 is determined again (step 02). Here, if there is no operation of the calculation key when setting the computer mode (operation of the calculation key once), the display mode for performing normal calculations is set (step 04). As a result, calculations are performed using a one-stage display, and the calculation results are displayed as shown in FIG. 3(a).

However, if the calculation key is operated twice in succession,
The mode is set to display in writing format. That is, the calculation formula is displayed in multiple stages, the numerical value is displayed together with the calculation symbol, and the calculation result is displayed as shown in FIG. 3(b) by operating the = key 112.

Control of Calendar Mode Explaining the calendar mode, the calendar mode is set by operating the calendar key 165.

In the flowchart shown in FIG. 2(a), when the calendar mode is set, a calendar display is performed according to the date information disclosed by the clock circuit 6. In other words,
The year, month, day, etc. counted by the clock circuit 6 are stored in the area 7A of the temporary storage register, and this content is read out. For example, the clock circuit 6 measures January 11, 1988, which is stored in the storage area 7A, and this date data is read out (step U2).

For the year of the Christian calendar read out from the area 7A, the day of the week (the day of the week of January 1st of the year) corresponding to the year of the Western calendar in the storage area 30A of the calendar storage ROM 3 is read. Based on this day of the week data, the dates of January are assigned to each day of the week and a calendar is displayed as shown in FIG. 6(a). Since this is January, the day of the week that year is 30A.
It can be easily displayed by performing calculations in relation to the day of the week. However, after February,
Perform and display the following calculations.

First, the read day of the week data ("5") for January 1st of the year is written into the area Xt of the - hour storage register (step U3). Then, the number of days until the month to display the calendar (0 for January, 3I for February)
, 60, etc. if it is March and the year is a leap year) and the number of days in June are read from the area 3013 of the calendar storage ROM 30, and the respective number of days data is stored in the area X2 of the register 7.
and written to X3 (step U4). Next step U
5, the data of areas XI and X2 are added, and the result of this addition is divided by 7. The remainder data resulting from the division by 7 is written to area X4 of register 7. That is, the data stored in area X4 is data representing the day of the week on the first day of the month, and if it is "1", it is Monday.

This calculates the day of the week data for the 1st of each month, and when displaying Sunday as the first day of the week, if the day of the week can be calculated, the 1st is substituted according to that day of the week and stored in area X3. If the number of days is allocated from the day of the week on the 1st, Figure 6 (a
) can perform a calendar display (step U6).

Here, according to the present invention, not only a simple calendar display but also a calendar display for January 1st of the year as shown in display parts a, b, and C.
Displays the number of days from the date indicated by the cursor, the number of days from the date indicated by the cursor to the last day of the year, and what week of the year the day indicated by the cursor is. This display is performed as shown below.

That is, as shown in the flowchart of FIG. 11(a), by adding the number of days data stored in X2 and the day specified by the cursor, January! It is displayed on the display section a as the number of days from the current day to the current day (step U7). Then, by subtracting the addition result of the above X2 and the day specified by the cursor from the number of days in the year, the number of days until the last day of the year is calculated, and this is displayed on the display (step U8 ) to be done.

In addition, in the week display on display section C, Fig. 1'1 (a
), it is determined whether the data stored in area x1 is before Wednesday (step U).
9) After that, in order to calculate one week from January 1st to the end of the week if it is before Wednesday, add 7 to the number of days data stored in area X2 and write it in X2 (step U10). And X! Add X2 and the day, perform 1, and divide this calculation result by 7.

Then, the calculation result is stored in the x5 area (step Ull
)Sashi, the remainder indicates the day of the week, but it is unnecessary in this case, so it is truncated. The contents of X5 are displayed on display section C, and this is displayed in reverse (step UI4)
be done.

However, if January 1st is after Thursday, it will be +7
Add the data of Xt and X2, etc. without performing -1
The result of dividing by 7 is written in area X5. and,
Determine whether the content of X5 is 0 or not (step U12),
If it is not 0, the contents of X5 will be displayed as shown in FIG. 6(a). If it is 0, the number of days until the last day of the previous year (366 days in a leap year) is read out from 30B, the data is stored in x2 (step u 13 ), and the above-mentioned calculation is executed. In other words, 1988
The date is the last week of the previous year, and a display indicating the 52nd week is displayed on the display section C in accordance with the calendar display.

Incidentally, in the calendar display, the display of January 16th is displayed in reverse (reverse), which indicates, for example, that it is a second schedule with a fixed date set every year. For example, birthdays, wedding anniversaries, national holidays, etc. At this time, if you specify the cursor on that day and operate the schedule key, the second schedule storage section 9
The contents of the schedule etc. stored in will be displayed. Then, by operating the cursor movement key 13, the contents of the schedule stored in the schedule storage section 8 are sequentially displayed.

In the above calendar display state, reading out the schedule will be described in detail when the schedule function is explained.

In addition, in this calendar display, the display shown in FIG. 6(a) is a display based on the information stored in -time storage register 7B. If it is desired to switch the display to the display shown in FIG. 6(b), control is performed according to the flowchart shown in FIG. 11(b). In other words, 5II
By operating the IFT key 12 and calendar key 165, the display switching mode is set. Then, the character input key S key (when Sunday is the first day of the week) or M key (when Monday is the first day of the week) is input (step V2). Then, in step V3 or V4, it is determined whether the S or M key has been input. If you press the S key, go to area 7B.”
If 0'' is the M key, 1 is stored in area 7B.

As a result, the information stored in the area 7B is used as shown in FIG. 6(a).
Or display (b) is selected.

Note that the calendar display may be one that can display weeks instead of one month as shown in FIG. 6(a).

Schedule input If the electronic notebook is used to store a schedule, operating the schedule key 164 will enter the schedule input mode. If the electronic notebook is in a state other than the calendar mode, operating the schedule key will correspond to the information stored in the area 7A of the temporary memory register that stores the year, month, and day counted by the clock circuit 6. The input screen for the schedule will be displayed. Here, if a schedule has been entered for that date, for example, the 4th
A schedule as shown in Figure (a) is displayed.

However, if no schedule has been input, only the year, month, day, and day of the week are displayed. Then, input the year, month and date including the date, input the start and end times of the schedule, input whether or not to output an alarm, and input the contents of the schedule. like this,
Input is similar to conventional electronic notebooks.

Schedule input will be explained according to the flowchart in FIG. 13. In the schedule mode (step Sl), the schedule contents are displayed by year, month, and day as described above (step S2). In this content display state, if a numerical value or the like is input instead of using the cursor movement key 13, it is processed as a date input (step S6). In this case, you will need to input the year, month, and day. When this human power ends,
The cursor is set to perform time-of-day operation. In other words, the cursor moves to that time display section. Therefore, it is sufficient to input the required start time (steps S7 and S8). When the manual input is unnecessary, the schedule content input process (SI5) is executed, and by operating the ENTER key + 21 after manually inputting the schedule content, the date is entered in the area 8A of the schedule storage unit 8, and the date is entered in the area 8F. Memorize schedule details.

On the other hand, if u/7 start time is to be input, the numerical value of the start time is entered manually, and if the start time is entered manually, it is determined whether or not to input the end time (step S9゜510). After the input processing, it is determined in step Sll whether or not an alarm is required. This is 5IIIFT
An alarm is set by operating the += key (step 513), and if the key is not operated, processing is performed as requiring no alarm output (step 512). That is, "0" is stored in the flag indicating the state of no alarm, that is, 8B of the schedule storage section 8. If an alarm is required, the flag is set to "■" and instructions are given to input the alarm time, etc., and the operation is performed manually (S14). When this input is completed, the schedule content input process is executed as described above. By operating the ENTER key, the date will be displayed in each area of the schedule RAM 8, the start time will be displayed in 8C, the end time will be displayed in 8D, and if an alarm has been set, the alarm time will be displayed in 8E, and the alarm time will be displayed in 8F. The contents of the schedule are memorized.

If the flag indicating an alarm is "°l", the CPU 5 outputs an alarm when the time measurement by the clock circuit reaches the alarm time. While searching for parts, an alarm is output when a match is detected.

Manual input of the second schedule It is also effective to manually input the schedule at a fixed date and time every year.

For that purpose, the input is 5IIIFT key 111
If the + schedule key 164 is operated, the second schedule input state is set. As shown in the flowchart in Fig. 14, depending on the operation status of the schedule key, the input status of dates and times to specify birthdays, holidays, wedding anniversaries, etc., and Mother's Day, etc., which are scheduled for Sunday of the week, etc. This is the switching setting and input when inputting Father's Day, etc.

First, when the second schedule mode (step Tl) is entered, the operating state of the schedule key 164 is determined (step T2), and if the schedule key is operated,
Mode manual processing letter! 2! (Step T3). Enter the letter to enter the day or specify the week - D of 12
Decide by operating the key or W key. If the D key is operated, the date input mode is determined and the mode is stored in the area 7C of the temporary storage register (steps T4 and T6). For example, "0" is stored. Also, if the W key is operated, "1" is stored in the area 7C (steps T5 and T7).
be done. When inputting a schedule by specifying this mode, if there is no operation of the schedule key, it is determined whether the date input or withdrawal input is performed by determining whether the area 7C of the - hour storage register is "0" (step T8). In the area 9A of the second schedule storage unit 9, information "0" indicating that the date is input in step T9, and in the area 9B.
The input month information (step Tl0) is stored in area 9.
The information on the day inputted in C (step T11) is manually stored in the area 9E (step T16), in which the contents of the second schedule for this day are manually stored by operating the ENTER key.

Also, if it is an input setting that indicates the week, "!" is placed in area 9A.
However, 9B contains the manually entered month, 9C contains the week information of the week of the month, and 9D contains the day of the week information.
Furthermore, the contents of the schedule are stored in 9E by operating the ENTER key 121 (steps TI2 to T16).

Schedule Output Control Particularly in calendar mode, when the schedule key 164 is operated, the schedule for the date specified by the cursor in the calendar display state is displayed with priority.

i.e. the calendar date (the day indicated by the cursor)
The schedule contents corresponding to are read out from the schedule storage section 8. For example, in the state shown in FIG. 6(a), the contents of January 11, 1988 are read out from the area 8C of the schedule storage section 8, the end time from 8D, and the schedule contents from 8E. , is displayed as shown in FIG. 4(a). In this display state, the cursor keys cannot be operated (especially the up and down movement keys 1).
32, 134), the immediately preceding schedule or the immediately following schedule currently displayed is displayed.

For example, if the previous display is the schedule display last stored on the previous day, and the next display is the schedule for that day, the next stored schedule content is read out and the schedule is If not, the next stored schedule content is read out and displayed.

In addition, in the calendar display state of FIG. 6(a),
If the highlighted date is specified with the cursor, the contents of the second schedule will be displayed with priority.

That is, when the schedule key 164 is operated, the tQ information corresponding to the date is read out from each area from the second schedule storage section 9 and displayed as shown in FIG. You can check whether it is a date, wedding anniversary, or other information. Further, by operating the cursor movement key 13, the contents of the preceding and following schedules are read out as described above.

At this time, if the contents of the second schedule are not stored on that day, the schedule storage section 8 is searched for that date, and if the schedule is stored, it is displayed.

In the calendar display state as described above, by operating the schedule key, the contents of the schedule storage section 8 or the second schedule storage section 9 are read out and displayed. In this display state, new schedule information can be manually created and stored.

Next, in the calendar display state, the contents of the schedule can be read out and displayed by operating the calendar key 165. This will be explained with reference to the flowchart in FIG. When the calendar mode (step Ul) is entered, a calendar is displayed (steps U15 and UI6) as described in the flowchart of FIG. 11(a). and calendar key 1
It is determined whether or not the operation 65 is performed (step U17).
be done. If the calendar key 165 is not operated, it is determined whether the cursor movement key 13 has been operated (step U18). If the cursor key is operated, the cursor is moved (step U19) to change the designated day. In other words, by appropriately operating the up, down, left, and right cursor keys 131 to 134, the cursor position moves according to the operation keys and is displayed. Here, cursor key 1
If you operate 32 and go beyond the day of the month currently displayed,
Operates to specify the 1st day of the next month (for example, February),
Displays the calendar for the month. In this case, Fig. 1f (
It is displayed according to the flowchart in a).

Furthermore, if there is no operation of the cursor keys, the calendar display continues. Although not described here, if the mode is not set for a predetermined period of time, a configuration may be adopted in which, for example, the calculation mode is automatically set preferentially. Alternatively, the electronic notebook may be configured to be turned on and automatically turned off if the electronic notebook is not used for a certain period of time.

Now, if the calendar key is operated while the calendar is being displayed, weekly information for the day indicated by the cursor will be displayed (step U20). Whether to display information for one week from that day or for the week starting from the Sunday that includes that day is determined by the system program and is not directly related to the present invention. In the weekly display, the contents of the schedule are displayed in accordance with the display of each day of the week and the day of the week, as shown in FIG. 5(a). In this display, the number of characters in one line of the display device 2 is determined, and a determined number of contents are displayed from the beginning. In this state, if you want to move to the date specified by the cursor, you can move it freely by operating the cursor keys (steps U22 and U23).

Then, with the contents of the weekly schedule displayed as shown in Figure 5(a), by operating the calendar key again (step U21), the daily information for the day specified by the cursor is displayed. Display (step U24)
be done. This display is displayed as shown in FIG. 5(b). If the calendar key 165 is operated again in this daily information display state, the display switches to the calendar display state shown in FIG. 6(a). On such a display screen,
The schedule cannot be done manually. Further, as shown in FIG. 5(b), the display section n displays, for example, the schedule "DIN".
This is a display that informs you that there is schedule information after "N". Therefore, use the cursor movement key 13 to specify the schedule after that, and if you move the cursor, the weekly schedule information after that will be displayed. It turns out.

Here, to display the schedule in calendar mode,
To determine whether or not the schedule stored in the schedule storage unit 8 or 9 corresponds to the month and day, search the storage area for the month and day, and if information corresponding to that is stored,
This will be displayed. However, in the calendar display, when displaying the schedule for the highlighted day, the contents of the schedule storage section 9 are read out with priority.

Schedule Time Display Control In the daily display information when displaying a schedule, the scheduled time of the schedule is displayed in a graph with the time displayed in hours on the horizontal axis, as shown in FIG. 5(b). There is. This will be displayed according to the input time information.

This will be explained in detail according to the flowchart in FIG. In the display of FIG. 5(b), the start time or end time for the second schedule ("5TAF") indicates a start time of 9:30 and an end of 11:00. That is, the start time and end time of the schedule in "5TAF" are manually entered and stored in areas 8C and 8D of the schedule storage section 8, and graphs are created based on this stored information.

That is, it is determined whether the time to be displayed is the start time (step W l ), and if the start time is 9:30, the minute data is outside the range of 00 to 29, so the tip position corresponding to 9 o'clock is set. displays a “-” graph (step W2
．． W4) Do it. Moreover, since the end time is based on If clock, the rear end position corresponding to 11 o'clock is """
(Steps W5 and W7).

By displaying the above, you can see whether it starts at 9:00 or 9:03.
You can clearly tell whether it starts at 0 minutes, ends at 11 o'clock, or ends after 11 o'clock (30 minutes). Here, if you enter the schedule time manually in 30-minute increments, you can easily determine whether it starts or ends on the hour or 30 minutes, making the time more accurate without having to enlarge the display screen. It becomes possible to distinguish between Further, as the symbols of the graph at the leading and trailing ends of the start and end, the above-mentioned symbols are just an example, and symbols that can distinguish these may be set. Also, by setting a large number of symbols, you can display more accurate time graphs. However, as the number increases, it may become difficult to determine which time each symbol corresponds to. Therefore, 15
The time may be set to a value that can be expressed in minutes.

The control clock for the clock function is set to that mode by operating the clock key 162, and the count contents by the clock circuit 6 that measures the time in the home area are displayed. An example of the display is shown in FIG. 7(a). Also, "World Clock Key"
63, the current time of the region (stored as address) stored in area 7D of the -time storage register is displayed as shown in FIG. 7(b). In other words, if the area corresponding to the address BO is specified on 7D as shown in FIG. 9, the time of the area at this BO address will be displayed first by operating the world clock key. If the information on this BO address is "LONDN", for example, the current time in that area is determined by the time difference between the clock circuit 6 that measures the time in the Bohm area and the Jl area (information in B3). By calculating this, the current time of "LONDN" can be displayed. Such calculations are performed in the same manner as in conventional world clocks, so their explanation will be omitted.

Then, in the time display of the world clock, search key 14
1,142, for example, if the area of the BO address is displayed in the storage unit 30C of FIG. 9, the area one above or one below is read out and displayed. The address of the displayed area is then rewritten in area 7D of the temporary storage register. Therefore, the next time the world clock key 163 is operated, the region stored in the 7D will be read out with priority, and the time for that region will be displayed by calculating the count time of the clock circuit 6 and the time difference. .

Here, as shown in FIG. 7, not only the region is displayed, but also the country name of the region is displayed at the same time. As shown in detail in FIG. 9, the area and country name are also stored in the storage area 30C of the calendar storage unit 30 in a corresponding manner.
It is stored in 0C-2 and 30C-3, and by reading it out, the name of the country is displayed along with the region. Therefore, it is recognized that times differ within the country, and it is possible to easily adjust the time in a desired region. You can also know the country in the area you searched for, and where it is located.
It's about to be considered.

In addition to displaying the time in each region of the world, the display section m also displays the time difference with your home region.

To display this time difference, for example, change your home region to NEW
YORK'', the time difference between this area and the reference area is stored in A3 of 30C-4 corresponding to the AO address, and if this time difference is stored as ``12:00'' for example. Also, in world clock mode,
When searching for "LONDN" and assuming that it is the BO address of the storage section, the area 83 of 30C-4 stores data such that the time difference of the reference area is "17:00", for example. This time difference is "NI4 YO" which is a demonstration
It is calculated that the time difference between "RK" and the searched area ("LONDN") is 5 hours, and this is displayed on the display section m.

As described above, since the time difference between different regions between the specified region and the searched and specified region is displayed, it is possible to easily recognize the time in the specific region based on the time difference. Since this is not an indication of the time difference of the reference area, it is necessary to know the time in a specific area by converting it to -tan base time and calculating the time difference between this base q time and the reference area of the specific area. Without,
It is very easy to recognize.

Time adjustment control To adjust the time, press 5IIIFT key 111 10 World clock key +
This is executed by the operation 63. This will be explained according to the flowchart in FIG.

First, use the key operations described above to enter the correction mode (step 11).
), and the time in the area of the address stored in 7D of the storage register 7 is displayed (step R4). If it is in this area or a predetermined area, time information will be input by operating the numerical keys without operating the search keys 141 and 142. However, if it is not the desired area,
By operating the search keys 141 and 142, predetermined areas are sequentially searched, and the time of each area is displayed (step R2°R3 or 114.R6). Therefore, once the desired area has been searched, numerical input of time information is performed, and when the input of the numerical information is completed, by operating the ENTER key 121, the clock circuit 6 corrects the input time. Can be rewritten to time information. This causes the clock circuit 6 to restart time counting according to the corrected time.

As described above, the address of the corrected area is stored in 7D of the storage register 7, and by operating the world clock key 163, that area is read out first.

Home region change control Next, the case of changing the home region will be explained. FIG. 17 is a flowchart showing an example of this. First, by operating the 5HIFT key-Ill clock key 162, the home region correction mode (step PI) is set. In this case, the previous home area is, for example, Figure 7 (
It is displayed in the state shown in a). The area to be changed is then searched for by operating the search keys 141 and 142 (steps P2, R3 or R5, R6). When the desired area is searched, the ENTER key is operated (step P7). Thereby, in order to count the time of the changed home area, the time of the displayed area is rewritten to the count time of the clock circuit 6, and the change of the home area is completed.

After the above operations are completed, the time counted by the clock circuit 6 can be changed by operating the clock key 162.
The home area is displayed as shown in FIG. 7(a).

<Effect> As explained above, according to the upper world clock according to the present invention,
By knowing not only the specified region but also the countries in that region,
You can recognize the approximate location of the area.

Furthermore, since the time difference between different regions is displayed, the time in one region can be easily determined based on the displayed time difference, so there is no need to search for one region.
